BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Sunpararekin’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new freely-branching and vining Mandevilla plants with numerous large attractive flowers.

The new Mandevilla plant originated from a cross-pollination in Higashiomi, Shiga, Japan in April, 2006 of a proprietary selection of Mandevilla hybrida identified as code number 02M5-1, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number MH51, not patented, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in October, 2007.

Asexual reproduction of the new Mandevilla plant by cuttings in Higashiomi, Shiga, Japan since October, 2007 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunpararekin’. These characteristics in combination distinguish ‘Sunpararekin’ as a new and distinct Mandevilla plant:

-   -   1. Upright and vining plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit, dense and bushy plant form.     -   4. Dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Long flowering period.     -   7. Large bright red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Flower petals of plants of the new Mandevilla are imbricate         whereas flower petals of plants of the female parent selection         are not imbricate.     -   2. Plants of the new Mandevilla and the female parent selection         differ in flower color as plants of the female parent have         lighter red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent selection. Plants of the new Mandevilla differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Leaves of plants of the new Mandevilla are smooth whereas         leaves of plants of the male parent selection are coarse in         texture.     -   2. Plants of the new Mandevilla and the male parent selection         differ in flower color as plants of the male parent selection         have deep red purple-colored flowers.

Plants of the new Mandevilla can be compared to plants of Mandevilla hybrida ‘Sunparasupre’, disclosed in U.S. Plant patent application Ser. No. 13/815,167. Plants of the new Mandevilla and ‘Sunparasupre’ differ primarily in growth habit as plants of the new Mandevilla have shorter lateral branches with longer internodes than plants of ‘Sunparasupre’. In addition, plants of the new Mandevilla have larger flowers than plants of ‘Sunparasupre’.

Plants of the new Mandevilla can be compared to plants of the Mandevilla ‘Sunparakama’, disclosed in U.S. Plant Pat. No. 22,366. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla differed from plants of ‘Sunparakama’ in the following characteristics:

-   -   1. Plants of the new Mandevilla had oblong-shaped leaves whereas         plants of ‘Sunparakama’ had elliptic-shaped leaves.     -   2. Plants of the new Mandevilla had broader flower petals than         plants of ‘Sunparakama’.     -   3. Plants of the new Mandevilla had wider flower throats than         plants of ‘Sunparakama’.     -   4. Plants of the new Mandevilla and ‘Sunparakama’ differed         slightly in flower color.     -   5. Plants of the new Mandevilla had longer peduncles than plants         of ‘Sunparakama’.
